In the unedited, photo it’s a bit more clear that the light yellow network of fibrous tentacles is actually a meandering aquatic plant floating in water – in this case, a pond – just beneath the surface.

In editing the photo, I wanted to bring out the contrast between the yellow plant and the greenish hue of the water. So I moved briskly to the electric end of the color spectrum and also applied some other filters to add a retro urban feel.

I sat quietly for a while looking at the edited photo and exploring my inner landscape in relation to it, asking myself how the colors made me feel, what, in the abstract, that yellow thing kind of looked like, and so on.

Then I listened to my intuition, which told me that the yellow tentacles looked like either a subway map or a medical image of a nerve cell ganglion – no, they looked like both at once!

The two contrasting interpretations of the photo’s subject practically handed me the two components of the haiku on a platter: “synapse,” as in a nerve cell synapse, and “the distant rumble / of the outbound train,” referring to the subway map interpretation of the yellow vine.
